Comment 5 for bug 1555299

When using 'Advanced install' user MUST edit kernel boot options first and provide valid MAC address of the network interface that should be configured as admin interface. That the main goal of this installation mode - configure one network interface as administrative using MAC address as a filter.

Here is how 'Advanced install' should be used:
* On 'Welcome to FUEL Installer' screen (Pic 1) select option 2 and press TAB to edit boot options
* In boot options find option 'ifname=adminif:XX:XX:XX:XX:XX:XX' and replace ONLY 'XX:XX:XX:XX:XX:XX' with a valid MAC address using the same notation - pairs of hexadecimal digits separated by a colon.
* Press <Enter> to start installation.
